What is the Northern Expressway?The Northern Expressway will be a new road initially joining the

Sturt Highway to Port Wakefi eld Road – and then linking to the

Port River Expressway. It will involve:

the construction of a new, two-way expressway standard

road between Gawler and Port Wakefi eld Road (approximately

23 kilometres), and

an upgrade of Port Wakefi eld Road from north of Taylor Road

to the Salisbury Highway (10 kilometres) to cater for future

traffi c volumes.

The Northern Expressway project is a joint initiative by the

Australian and South Australian Governments under the AusLink

program. It will be the largest road construction project in the

state since the 1960s.

Why do we need the expressway?The aim of the Northern Expressway is to:

improve the northern regional economy, and

improve safety and reduce the environmental impact of

freight transport and commuter traffi c on suburban areas

and regional communities.

The Northern Expressway will reduce driving time and

increase safety for travellers from the Mid-North, Riverland

and regional communities. People who commute between

Gawler and the Port of Adelaide, and the western and southern

suburbs of Adelaide will also benefi t.

The route will reduce truck movements along Main North Road

and Salisbury Highway. The expressway will improve access

to Adelaide for freight transport travelling via the Sturt Highway.

This includes freight coming from key areas such as the

Barossa Valley and the Riverland. Once linked with the

Port River Expressway, there will be predicted travel time savings

of up to 20 minutes between the Sturt Highway at Gawler and

the Port of Adelaide – South Australia’s main shipping port.

The Northern Expressway contributes to AusLink’s key

objective of assisting national economic and social

development aimed at improving the effi ciency, safety and

reliability of the national transport network. This includes

improving freight effi ciency and reducing travel time between

Gawler and Outer Harbor.

It will also contribute towards the following targets in

South Australia’s Strategic Plan:

promoting economic growth

expanding export potential for the State

providing strategic infrastructure

providing infrastructure to support communities

in regions.

Gawler to Port Wakefi eld Road section:

four lane, two-way expressway with divided roadway

speed limit of 110km/hr

full speed connection at Gawler, linking with the

Gawler by-pass

entry to the expressway via interchanges

overpasses across the expressway

changes to the road network

Upgrade to Port Wakefi eld Road section (Taylor Road to Salisbury Highway):

additional traffi c lanes on Port Wakefi eld Road in

some sections

improvements to some junctions

install new and upgrade existing traffi c lights to

increase capacity

improvements to the Salisbury Highway/

Port Wakefi eld Road bridge

improve safety by removing some right turn access

points by: closing some median openings, providing

left in/left out arrangements for connecting roads,

and adjusting U-turn facilities.

What are the key features?

What are the benefi ts?The Northern Expressway will:

provide signifi cant economic benefi ts to the state

improve traffi c conditions for local residents in Angle Vale

and the northern suburbs near Main North Road

make roads safer by reducing freight, in particular Angle Vale

and Heaslip Roads

provide a quicker and safer connection with suburban

destinations such as Adelaide Airport, shopping centres,

sports stadiums, beaches, residences and businesses

connect to the new Port River Expressway, allowing drivers

to use on-off connections at South Road and Hanson Road

as well as Port Adelaide

allow travellers, and particularly freight traffi c, to avoid any

traffi c congestion along the existing Main North Road

help to reduce vehicle pollution emissions due to smoother traffi c

fl ow along the Northern Expressway and Main North Road.

Where will the expressway go?The proposed route for the Northern Expressway is shown on

the inside of this brochure. The proposed route was developed as

a result of a planning study which has been ongoing since 2003.

The study considered a variety of routes and looked at how to:

improve safety for all road users

improve freight effi ciencies

reduce effects on local and regional traffi c networks

consider the needs of landowners and local residents

reduce effects on land productivity

reduce effects on indigenous and non-indigenous heritage sites

avoid splitting up communities

reduce environmental effects such as changes to noise,

air and water quality.

Contributors to the planning process included State and Australian

government departments, local councils, industry and local

business organisation representatives. Community consultation on

the proposed route is an important next step. The proposed route

will now undergo an environmental assessment.

Following this assessment, a fi nal decision on the proposed route

will be made. The proposed project is subject to the fi nalisation of

agreed funding between the State and Australian governments.

How will environmental effects be considered?An environmental assessment has commenced and will

continue during the community engagement process.

It will identify and quantify the environmental, social and

economic effects of the Northern Expressway proposal.

The investigations will relate to technical areas such as:

noise

air quality

cultural heritage

fl ora and fauna

visual effect

and landscaping

Project team members working in the area will be clearly

identifi ed. Their presence will not mean that any particular

property is to be affected by the project.

The environmental report will describe the Northern

Expressway, summarise its effects and describe the

proposed ways to avoid or minimise any adverse effects.

It will be available for public comment in the fi rst half

of 2007. Comments received from the community will

be considered and inform any revision of the concept

design. A supplementary report document will also

be prepared.

What happens if the proposed route goes through my property?

Some properties will need to be purchased by the Department

for Transport, Energy and Infrastructure (DTEI) so that the

Northern Expressway can be constructed. The Department

is authorised under the Highways Act 1926 to acquire land

required for road development purposes.

Approved guidelines will be followed when contact is made

with potentially affected property owners or occupiers.

Staff of DTEI will individually contact these people.

Information about property owner rights will be provided.

If you believe that your property might be acquired,

and you have not yet been contacted directly, then please

contact the Northern Expressway team on 1300 658 621.

Community engagement during the environmental assessment and response process will occur from November

2006 until mid-2007. Its purpose is to obtain feedback, identify issues, and provide input into the environmental

assessment process. Dates and times for displays and open days will be advertised in local papers and will be

available on the Northern Expressway website.
